单选题 Last weekend Kyle MacDonald in Montreal threw a party to celebrate the fact that he got his new home in exchange for a red paper clip. Starting a year ago, MacDonald bartered the clip for increasingly valuable stuff, including a camp stove and free rent in a Phoenix flat. Having announced his aim (the house) in advance, MacDonald likely got a boost from techies eager to see the Internet pass this daring test of its networking power. "My whole motto (座右铭) was 'Start small, think big, and have fun', "says MacDonald, 26, "I really kept my effort on the creative side rather than the business side." Yet as odd as the MacDonald exchange was, barter is now big business on the Net. This year more than 400000 companies worldwide will exchange some $10 billion worth of goods and services on a growing number of barter sites. These Web sites allow companies to trade products for a virtual currency, which they can use to buy goods from other members. In Iceland, garment- maker Kapusalan sells a third of its output on the booming Vidskiptanetid exchange, earning virtual money that it uses to buy machinery and pay part of employee salaries. The Troc-Services exchange in France offers more than 4600 services, from math lessons to ironing. This is not a primitive barter system. By creating currencies, the Internet removes a major barrier—what Bob Meyer, publisher of BarterNews, calls "the double coincidence of wants." That is, two parties once not only had to find each other, but also an exchange of goods that both desired. Now, they can price the deal in virtual currency. Barter also helps firms make use of idle capacity. For example, advertising is "hugely bartered" because many media, particularly on the Web, can supply new ad space at little cost. Moreover, Internet ads don't register in industry-growth statistics, because many exchanges are arranged outside the formal exchanges. Like eBay, most barter sites allow members to "grade" trading partners for honesty, quality and so on. Barter exchanges can allow firms in countries with hyperinflation or nontradable currencies to enter global trades. Next year, a nonprofit exchange called Quick Lift Two (QL2) plans to open in Nairobi, offering barter deals to 38000 Kenyan farmers in remote areas. Two small planes will deliver the goods. QL2 director Gacii Waciuma says the farmers are excited to be "liberated from corrupt middlemen." For them, barter evokes a bright future, not a precapitalist past.

单选题{{B}}11-15{{/B}} After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: the damage and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25, 000 victims. Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes. Despite the good news, civil engineers are not resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place. In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports, called smart buildings. The structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction. The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

单选题 The key position and role of women in the process of development is increasingly being recognized. Although the three great World Conferences of Women were more concerned with recognizing and compiling approaches to emancipation we can currently confirm a general sharpening of awareness. It has become clear that the Third World cultures, in earlier times strongly matriarchal, have been weakened in this respect by the methods of colonial education which are almost exclusively directed towards the male. Of the many criticisms of this situation let one voice be heard: "Development education' groups and programs are very much male dominated and lack woman's perspective". So, too, the hopes placed in vocational training--"vocationalization'--as an aid to equality have been disappointed since this in its turn was to large extent focused on the male. In these circumstances we should not be surprised that until now women have participated least in the educational processes which have been introduced. Only 20% attend primary school and the percentage of those who leave early is highest among girls. Because of the lack of basic training only around 10% take part in Adult Education programs. Hence it is vitally important to secure a turning point by increasing the awareness of the need for education. The International Conference at Jomtien in 1990 provided the solution to this: "A more educated mother raises a healthier family. She has fewer and better educated children. She is more productive at home and in the workplace and is better able to get further education." Many problems in school are consequences of incorrect or improperly balanced nutrition combined with .inadequate hygiene. Together these factors can lead to failure to keep pace in school. Hence even primary education for girls should be directed towards the basic needs and necessities and provide answers which are as simple as possible. In rural districts such answers will be different from those given in urban areas. The education of girls and women must to a large degree be an education for the life they will lead, tailored to a woman's position. In saying this we are in fact demanding that the education of women, like all educational work in the Third World, should be an integrated part of the community. Consequently there are many partners in this process school, family, small businesses, governmental and non-governmental organizations. The educational skill consists in keeping this interplay active in such a way that there is no deficiency in material content. An important consequence of this is the awakening of the desire to question, which, on the one hand presses for further education and on the other hand for its practical application.

单选题 When Thomas Keller, one of America's foremost chefs, announced that on Sept. 1 he would abolish the practice of tipping at Per Se, his luxury restaurant in New York City, and replace it with a European--style service charge, I knew three groups would be opposed: customers, servers and restaurant owners. These three groups are all committed to tipping—as they quickly made clear on Web sites. To oppose tipping, it seems, is to be anticapitalist, and maybe even a little French. But Mr. Keller is right to move away from tipping—and it's worth exploring why just about everyone else in the restaurant world is wrong to stick with the practice. Customers believe in tipping because they think it makes economic sense. "Waiters know that they won't get paid if they don't do a good job" is how most advocates of the system would put it. To be sure, this is a tempting, apparently rational statement about economic theory, but it appears to have little applicability to the real world of restaurants. Michael Lynn, an associate professor of consumer behavior and marketing at Cornell's School of Hotel Administration, has conducted dozens of studies of tipping and has concluded that consumers' assessments of the quality of service correlate weakly to the amount they tip. Rather, customers are likely to tip more in response to servers touching them lightly and leaning forward next to the table to make conversation than to how often their water glass is refilled—in other words, customers tip more when they like the server, not when the service is good. Mr. Lynn's studies also indicate that male customers increase their tips for female servers while female customers increase their tips for male servers. What's more, consumers seem to forget that the tip increases as the bill increases. Thus, the tipping system is an open invitation to what restaurant professionals call "upselling": every bottle of imported water, every espresso and every cocktail is extra money in the server's pocket. Aggressive upselling for tips is often rewarded while low-key, quality service often goes unrecognized. In addition, the practice of tip pooling, which is the norm in fine-dining restaurants and is becoming more common in every kind of restaurant above the level of a greasy spoon, has ruined whatever effect voting with your tip might have had on an individual waiter. In an unreasonable outcome, you are punishing the good waiters in the restaurant by not tipping the bad one. Indeed, there appears to be little connection between tipping and good service.

单选题While still in its early stages, welfare reform has already been judged a great success in many states—at least in getting people off welfare. It"s estimated that more than two million people have left the rolls since 1994. In the past four years, welfare rolls in Athens County have been cut in half. But 70 percent of the people who left in the past two years took jobs that paid less than $ 6 an hour. The result： The Athens County poverty rate still remains at more than 30 percent— twice the national average. For advocates (代言人) for the poor, that"s an indication that much more needs to be done. "More people are getting jobs, but it"s not making their lives any better," says Kathy Lairn, a policy analyst at the Center on Budget and Policy Priorities in Washington. A center analysis of U.S. Census data nationwide found that between 1995 and 1996, a greater percentage of single, female-headed households were earning money on their own, but that average income for these households actually went down. But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory. "Welfare was a poison. It was a toxin (毒素) that was poisoning the family," says Robert Rector, a welfare-reform policy analyst. "The reform is changing the moral climate in low-income communities. It"s beginning to rebuild the work ethic (工作道德), which is much more important. " Mr. Rector and others argued that once "the habit of dependency is cracked," then the country can make other policy changes aimed at improving living standards. (286 words)

单选题Passage 7 No reference book, perhaps no book of any kind except the Bible, is so widely used as "the dictionary". Even houses that have few books or none at all possess at least one dictionary; most business offices have dictionaries, and most typists keep a copy on their desks; at one time or another most girls and boys are required by their teachers to obtain and use a dictionary. Admittedly, the dictionary is often used merely to determine the correct spelling of words, or to find out the accepted pronunciation, and such a use is perhaps not the most important from an intellectual point of view. Dictionaries may, however, have social importance, for it is often a matter of some concern to the person using the dictionary for such purpose that he should not suggest to others, by misspelling a word in a letter, or mispronouncing it in conversation, that he is not "well-bred", and has not been well educated. Yet, despite this familiarity with the dictionary, the average person is likely to have many wrong ideas about it, and little idea of how to use it profitably, or interpret it rightly. For example, it is often believed that the mere presence of a word in a dictionary is evidence that it is acceptable in good writing. Though most dictionaries have a system of marking words as obsolete, or in use only as slang, many people, more especially if their use of a particular word has been challenged, are likely to conclude, if they find it in a dictionary, that it is accepted as being used by writers of established reputation. This would certainly have been true of dictionaries a hundred years or so ago. For a long time after they were first firmly established in the eighteenth century, their aim was to include only what was used by the best writers, and all else was suppressed, and the compiler frequently claimed that this dictionary contained "low" words. Apparently this aspect of the dictionary achieved such importance in the mind of the average person that most people today are unaware of the great change that has taken place in the compilation of present-day dictionaries. Similarly, the ordinary man invariably supposes that one dictionary is as good and authoritative as another, and, moreover, believes that "the dictionary" has absolute authority, and quotes it to clinch arguments. Although this is an advantage, in that the dictionary presents a definition the basic meaning of which can't be altered by the speaker, yet it could be accepted only if all dictionaries agreed on the particular point in question. But ultimately the authority of the dictionary rests only on the authority of the man who compiled it, and, however careful he may be, a dictionary-maker is fallible: reputable dictionaries may disagree in their judgments, and indeed different sections of the same dictionary may differ.
